Arterial Development of the Limbs

(See also: Adult Upper Limb Arteries)

Discussion: Upper Limb Development

  • subclavian artery projects into the early upper limb bud & forms subclavian-axillary-brachial  trunk;
  • its distal portion becomes interosseous artery that initially supplies plexus of arteries in the primitive hand;
  • deep branch of brachial artery  & arteries about shoulder & elbow arise relatively late as branches of primary axial vessel;
